- Description: A large piece of petrified wood discovered near the petrified forests of Arizona. This extinct conifer species, Araucarioxylon arizonicum, is the state fossil of Arizona. The rarity and attractiveness of this specimen is due to several factors. Its size is very unusual, it is cut lengthwise and polished to reveal the spectrum of colors for which the site is so famous, and the texture around the edges has been preserved.
- Additional information: Petrified wood, fossil formed by the infiltration of minerals into the spaces between and within the cells of natural wood, usually silica (silicon dioxide, SiO2) or calcite (calcium carbonate, CaCO3). The petrified forests of the Western United States are silicified wood in which the tree tissue has been replaced by chalcedony (cryptocrystalline quartz). Often this replacement is so accurate that both the internal structure and external shape are faithfully reproduced.
